So it might be worth investigating why the two different processing
paths in `irq_startup()` cause this problem. I saw that Inochi
submitted a patch titled "irqchip/sifive-plic: Respect mask state when
setting affinity." Can we assume that simply applying this patch will
resolve the current issues with the SG2044? Do we also need to
consider introducing changes to the startup/shutdown functions of the
plic?
Sorry, please ignore my question. I looked at the patch again today and
it is still necessary to introduce startup/shutdown for plic.
Thanks,
Chen
